Where is the input to name radio in the radio name field

In my ap under wireless interfaces the column for radio name shows the mac address. Where can I input a name for this field? I’ve searched high and low buy no luck. I assume I do in the subscriber radio.

ROS 4.6

Perform this command in the subscriber unit.

/interface wireless set 0 radio-name=SomeName

It’s in the Advanced mode in Winbox:
